Quadra Recessed luminaires Lighting characteristics Lens system The innovative lens system of Quadra reduces the height of the recessed luminaires considerably. The lens system made of optical polymer is highly efficient and works on the principle of total internal reflection. As with the other LED lenses, this system has also been developed exclusively by ERCO and is produced in-house.
Alignment of the lens system The alignment of the oval beam of Quadra lumi naires with oval flood lens system is determined by the mounting position of the luminaire. The lens system is provided with a bar for precise marking.
Light guidance The lens system made of optical polymer is char acterised by supe rior efficiency and a very precise and uniform beam.
Lens system wide flood The wide beam, rotationally sym metrical light distribution is ideal for efficient general lighting in conference rooms, sales areas or traffic zones. The cross baffle additionally ensures good visual comfort.
To give a f lexible, flood illumination of s urfaces and spatial zones, especially in retail p resentation. Beam angle > 80°.
Lens system oval flood The axially symmetrical light dis tribution provides efficient illu mination for halls and corridors and for tables or shop displays. The cross baffle ensures good visual comfort.
The oval flood lens system pro duces an oval beam of about 45° by 90°. Its orientation is determined by the luminaire’s mounting posi tion.
